Concrete Scanning with Ground-Penetrating Radar



GPR Concrete Scanning Services

Concrete Scanning with ground penetrating radar (GPR) to verify any found anomalies in and under a concrete slab, ceiling or walls is good practice. The GPR transmits a signal/radio-waves down into the concrete. As the signal travels through the concrete, if the signal hits or bounces off an object, the signal bounces back up and is reflected on a screen for the technician to see the found anomaly.

The GPR is also able to “see” just a little past the bottom or back side of the concrete. This is how it is able to “see” voids and conduits laying on the gravel just under the slab or a pipe mounted on the back side of a concrete wall.

The found anomalies are marked on the concrete to form a grid/pattern. We are also able to determine the depth of the grid or found anomalies. This helps place the grid in the top, middle or the bottom of the slab.
We use the Geophysical Survey Systems Inc. (GSSI) ground penetrating radar systems for both concrete scanning and underground utility location. We figure if this equipment is good enough for
NASA to put it on the MARS Rover, then it will work for us!

What is Concrete Scanning?

Concrete scanning is basically the practice of finding objects and subsurface hazards using GPR aka Ground penetrating Radar technology. GPR concrete scanning can help detect pipes, conduits, rebar, post tension cables, utilities, live wires etc.

Why Scan Before You Drill?

How concrete scanning with GPR works

Ground penetrating radar (GPR) is a non-destructive technology that will allow you to “see” underground and through concrete. The radar signal bounces off the subsurface material and reports back where the experienced technician interprets the data in order to determine what material is in the concrete.

Concrete scanning offers accurate results for informed decision making. Our techs can also scan concrete walls to determine rebar or conduit location.
